I want to do an animation with several image-files, and for this the AnimationDrawable works very well. However, I need to know when the animation starts and when it ends (i.e add a listener like the Animation.AnimationListener). After having searched for answers, I'm having a bad feeling the AnimationDrawable does not support listeners..Does anyone know how to do frame-by-frame image animation on Android?

How do i pause frame animation using AnimationDrawable?
View 1 Replies View RelatedI'm trying to draw a "gauge" on the screen with information from various sensors. I have a class that extends Drawable and a custom view that during construction creates a new AnimationDrawable and sets the only frame to my custom Drawable. I then start the AnimationDrawable from my Activity onWindowFocusChanged method. My custom Drawable onDraw method is only called once though. Is that by design (as in onDraw is called for each frame once and it's cached and shown over and over) or am I doing something wrong?
CODE:..................
There's already been some discussion of this, in various lists and blogs. I finally got an AnimationDrawable to work, but I cannot start it from onResume. I can start it from a timer that onResume starts, or an onClickHandler.
I've poked around the source a bit and I can't figure out, specifically, what state the view has to be in, in order for the background AnimationDrawable to start.
Can anyone enlighten me?
I'm fading out an imageview with alpha animation. I'd like the image to stay transparent after the animation. Tried with different combinations of fillAfter and fillEnabled, no luck. How can this be achieved?
View 1 Replies View RelatedI'm trying to recompile AnimationDrawable class ( source code tooked from android source ) but I get some errors...
It says "The constructor DrawableContainer.DrawableContainerState (AnimationDrawable.AnimationState, AnimationDrawable) is undefined". Any ideas how to fix it?
Yesterday I post this : http://groups.google.fr/group/android-developers/browse_thread/thread...
but today this problem is not resolved and I think that the problem is an issue between TanHost component and Animationdrawable.
I tried a lot of thing, but the start() method makes nothing. The first drawable is displayed and that's all.
I would like to know if somebody can do a test to confirm it, I'll post a bug just after.
How to know the list of available extra for a intent?For example, I want to know all available extra for ACTION_BATTERY_CHANGED.

View 9 Replies View RelatedI use the gallery view extensively as a full screen pagination mechanism. It works really well for me without having to create a brand new control.
I would like to add a little elasticity at the ends (much like the iPhone homescreen). How could I go about doing this? Any hint as to which method I would need to override/modify?
I have a strange issue - from time to time the animation that should fade out my control (ImageButton) does not kick in immediately. I am using the fadeout animation to hide it and then in myListener on its end (onAnimationEnd) I put new resource as the image on the button.
Somewhere in my app code:
Animation a = AnimationUtils.loadAnimation(this,R.anim.fadeout); a.setAnimationListener(new myListener(location)); buttons[location].setAnimation(a); a.startNow(); // regardless if its start() or startnNow() it will work in most of the cases but not 100% reliable I actually can see in debug Log when its late, happens after few more clicks
Then in myListener.onAnimationEnd(Animation a):buttons[location].setImageResource(R.drawable.standard_button);
Seems there is a rule that the every 4th or 5th animation does not start ...
I am creating a button programmatically. It is rounded and has a gradient background, and works fine and looks nice, but I couldn't do two things I wanted:
Set a 1 pixel stroke with a given color. I tried getPaint().setStroke(), but couldn't figure how to set the stroke color. How should I do it?
Align the gradient to the bottom of the button, no matter what height it has. Is this possible?
For reference, this is the code I'm using:

is there a way to mass text to people without people knowing its a mass text (aka see that isent to multiple contacts, etc)?
im on a galaxy s3 but i have heard that iphones can see multiple contacts if they receive a mass text and can even reply all. ouch!??
also, how do i make it so the mass text sends to each person individually in its own separate thread? ive sent to a few people at oncei n the past and all it did was create a single thread on my phone with all the contacts on it.
I am having difficulties with the lifecycle of the opengl context. While rendering my scene and the user hits the back button, home button or another application opens in front of my application, my app is still running in the background.
So when my application comes to the foreground later on (user relaunches it or the app that was opened on top of it finishes), my application crashes and leaves me nothing but a GL stack trace which i can't properly decipher.
For rendering i use the GLSurfaceView and therefore delegate the onPause and onResume. The crash happens on the first call to glDrawElements(..).
I have tried to reload my resource (geometry/textures etc.) on onSurfaceChanged but with or without reloading... The problem persists.
This behavior can be observed on all AVD versions of the emulator as well as on the G1.
Here is the gl stacktrace i get.

I created an application which is displaying camera preview. When the application terminates I noticed that some processes are still running. Also if I try to run the original camera application it displays an error (obviously due to the active process which belongs to the custom application).
Does anyone know how to release all resources when application ends?
I have an already built application and I want to add a feature that has to be started when a call ends.
How can I achieve that?
I thought that declaring in my manifest something like this
CODE:............
Could be enough, but what kind of intent I have to put on the filter?
Looking in the documentation I found only the intents that detects when a call is started.
It happens that the user click on enter where i dont want to include it as a part of my input the string can end with 3 times so just replacing one wont do the job
My solution was:

Or just to point there without the new but i want later to dump the garbage. Or at least to dump values to the gc now ....
Im tring to simulate a slideup animation.The idea is to slideup and slidedown the tablelayout with the id searchForm when pressing the button so that i can use the extra space for a list.

I have an application that consist of several Activities. When the application starts, some alarms are scheduled using AlarmManager and some services are started:
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
a.setInexactRepeating(...)....
I would like to know any way to guarantee every service is stopped and every alarm is unscheduled when the user exits the application. The problem is that the user can leave the application from different Activities, and I don't like the idea of overriding the onDestroy method in every Activity. Is there any known Intent I can receive when the application ends? I've also found that an Android application can have a class that extends from Application, with a onTerminate method:
public class MyApplication extends Application {
@Override public void onTerminate() {
... } }
But the documentation is very clear: "never depend on this method being called; in many cases an unneeded application process will simply be killed by the kernel without executing any application code".
I'm looking for a way to resume my activity (which makes phone call) after call ends by user. Currently after user ends a call, it always returns to the phone's native call-log screen instead of the activity that originated the call. Is there any way to prevent or customize this?
View 3 Replies View RelatedI am using a progress bar in android, so that till my data is loaded, user is getting a proper feedback of what is going on.
The code for the bar is below:
CODE:............
The setSelected() method is inserting data into an array list, and then creating an array adapter and then using a list view to show those items. so when I put the setSelected() method in progress bar, it shows the loading circle, but once loading is done. Nothing is displayed in listview. But if I take out progress bar code (thread and run method), and simply call setSelected() method, the listview successfully declares the data. so far it concludes that the progress bar code is doing some thing...so wanted to know am I missing something to add in or take out from the code. I need to the show progress bar as I am reading data from online source and it takes time , which may make user uncomfortable.
